Routing Engineer 80% - 100% – Luzern | JobRevolt

Über den Job

You will be the architect of our map's intelligence, building the brain that powers our next-generation navigation experience. We aren't just finding the shortest path; we're creating a deeply personalised, multi-modal, and predictive routing engine from the ground up. This is a unique opportunity to solve complex algorithmic challenges and build a system that learns from every journey, powered by cutting-edge research and high-performance code.

Aufgaben

Designing and building a highly customisable engine, with the choice to extend an existing open-source project (like OTP, Graphhopper, Valhalla) or build our own to meet unique product needs
Designing clean, scalable routing APIs and collaborating with backend and mobile engineers to ensure they are robust and easy to use
Contributing across the stack by applying your engineering skills to our backend services or geospatial data processing pipelines
Creating the foundation for our AI-powered personalisation, where edge weights (speed, cost, preference) are dynamically adjusted for each user
Implementing complex multi-modal routing logic that can seamlessly combine walking, public transport, and ride-sharing into a single, optimised journey
Over time solving for modern transport challenges, such as building Electric Vehicle (EV) routing that intelligently incorporates charging stops, battery levels, and station availability
Developing and optimising core routing algorithms like A*, Contraction Hierarchies (CH), or other speed-up techniques for continental-scale networks
Building the testing and verification harness that keeps routing correct such as golden-route regression suites, invariant checks (e.g. triangle inequality, symmetry where expected), and benchmarks that catch performance regressions as the graph and algorithms evolve

Profil

A portfolio or GitHub profile showcasing strong projects in algorithms, data structures, or systems programming
Deep proficiency in a high-performance language, specifically C++, Java or Rust
Proven experience implementing and working with graph algorithms, particularly for routing (e.g., Dijkstra, A*, CH, Isochrones)
Familiarity with the challenges of routing on real-world data like OpenStreetMap (OSM)
Experience in API design and a solid understanding of how to build scalable, low-latency web services
A "T-shaped" or "tree-shaped" mentality, with a genuine interest in contributing to different parts of the product
3+ years experience in a professional environment with a demonstrable record of shipping production software
A rigorous approach to correctness and testing, with experience verifying algorithmic output where the "right answer" is non-trivial (e.g. regression testing, property-based testing, or validating against a reference implementation)
